Offering apx 250 ft of Flathead River frontage, this exceptional 28+ acre homestead-era property presents a rare blend of privacy, legacy, and opportunity just minutes from Kalispell. A U-shaped dock with two pontoon-sized boat bays enhances the riverfront recreational access. Built in 1905, the 1.5-story farmhouse features 4 bedrooms & 3 bathrooms, reflecting Montana’s early settlement character while offering functional living space. This legacy property combines productive land, multiple outbuildings, and significant river frontage, creating flexibility for a luxury riverfront estate, working agricultural operation, recreation-focused retreat, or generational holding. The Flathead River setting offers boating, fishing, and wildlife viewing directly from the property, while proximity to Kalispell provides convenient access to services, dining, and the airport. A truly rare opportunity to own a substantial riverfront holding with history, infrastructure, and enduring value. Additional improvements include a 768 sq ft finished garage, a 2,100 sq ft implement shed, a newer 1,872 sq ft shop with attached 432 sq ft lean-to, two 384 sq ft steel storage sheds with concrete floors & overhead doors, & another 160 sq ft shed. 6 grain bins with aerators offer approximately 60,000 bushels of capacity. Plus 4 separate water rights convey. With expansive acreage, premier river access and historic roots, this property offers exceptional versatility for recreation, agricultural use, or long-term investment. Though early legal homestead documentation may reside in county archives, the Sonstelie family name has been present in Kalispell since at least the late 1800s. Over the decades, generations of the family have worked, lived, and shaped life in the valley — from agricultural enterprise to community leadership. The very road on which this property sits carries that legacy forward, anchoring this land in local history as surely as the roots that spread across these 28+ acres.
